it all depends what you are going to do. If you are going off rode alot
and jumping it is worht it. if you are jist using it on street it ant. If your
engen and seat are about 6-9 inches apart, you have a steel seat or
bracings to weld a shock to and you can weld you cut the frame behind
the seat and have a pece of pipe cut into 3 sections with a road thrugh it
as a hinge the midle pece welded to the front and the other 2 on the
back pece then make a shock mount that is centerd in the frame or 2 on
the outsides. this is the esiest way if you are retrofiting a old frame.
(note you may have to modify the brake and gas controls so the lines
whether you have rods for conrtols or fluid controls so the work.)
